Abstract
Abstract The invention relates to a transportable breakwater comprising a plurality of floating units, each unit having a horizontal finlike protrusion which rotates to a vertical position for intercepting waves when the unit is tipped leeward by wave action. Mooring blocks placed in tandem and the connecting chains permit the floating units to yield gradually to oncoming waves.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
An offshore breakwater comprising: a. a plurality of buoyant units, each of said units having a substantially horizontal portion above the water surface and an integral depending ballast portion below the water surface, said horizontal portion having a protrusion projecting beyond said ballast portion into the direction of oncoming waves, said depending portion having diverging generally concave opposed surfaces coextensive with said horizontal portion; b. means flexibly interconnecting said units; c. an internal void in each of said buoyant units; and d. anchoring means flexibly connected to the bottom of said depending ballast portion of each of said buoyant units to limit lateral movement of said buoyant units during wave action and permit rotational movement of said substantially horizontal protrusion to a vertical position upon impact by wave action.
Claim 2
Dependent Claim
129 words
An offshore breakwater comprising: a. a plurality of buoyant units, each of said units having a substantially horizontal portion above the water surface and an integral depending ballast portion below the water surface, said horizontal portion having a protrusion projecting beyond said ballast portion into the direction of oncoming waves, said depending portion having diverging generally concave opposed surfaces coextensive with said horizontal portion; b. means flexibly interconnecting said units; c. an internal void in each of said buoyant units; and d. anchoring means flexibly connected to the bottom of said depending ballast portion of each of said buoyant units to limit lateral movement of said buoyant units during wave action and permit rotational movement of said substantially horizontal protrusion to a vertical position upon impact by wave action.
Claim 3
Dependent Claim
57 words
An off-shore breakwater as recited in claim 1 wherein said anchoring means comprises a plurality of groups of tandemly connected, submerged mooring blocks, each group of tandemly connected blocks aligned in a direction perpendicular to the alignment of said buoyant units whereby wave action produces gradual movement of said Blocks in the direction of said wave action.
Claim 4
Dependent Claim
57 words
An off-shore breakwater as recited in claim 2 wherein said anchoring means further comprises: a. chains connecting said ballast portion of each of said buoyant units to a yoke ring positioned equidistantly between adjacent ends of said buoyant units; and b. a chain connecting each of said groups of tandemly connected mooring blocks to a yoke ring.
Claim 5
Dependent Claim
146 words
A buoyant unit comprising: a. a mass having a base portion with an outwardly curved surface and an upstanding portion integral with said base portion; b. an internal void in said mass; c. said upstanding portion having a pair of bounding surfaces joined at one edge and diverging from said edge in opposed generally concave configurations and at an opposite edge joining said base portion; d. a first one of said concave surfaces having a larger radius of curvature than the opposing surface; and e. an elongated projection formed by the juncture of said base portion and said upstanding portion and bounded on one side by the curved surface of said base portion and on the opposite side by the concave surface having the greater radius of curvature, wherein said elongated projection protrudes horizontally above a water surface when said buoyant unit is floated in water.
Claim 6
Dependent Claim
146 words
A buoyant unit comprising: a. a mass having a base portion with an outwardly curved surface and an upstanding portion integral with said base portion; b. an internal void in said mass; c. said upstanding portion having a pair of bounding surfaces joined at one edge and diverging from said edge in opposed generally concave configurations and at an opposite edge joining said base portion; d. a first one of said concave surfaces having a larger radius of curvature than the opposing surface; and e. an elongated projection formed by the juncture of said base portion and said upstanding portion and bounded on one side by the curved surface of said base portion and on the opposite side by the concave surface having the greater radius of curvature, wherein said elongated projection protrudes horizontally above a water surface when said buoyant unit is floated in water.
